HL7 releases FHIR 4
January 02, 2019 / Tom Sullivan
Health Level Seven announced on Wednesday that a new version of its interoperability specification is now available. Many in the healthcare industry have been eagerly awaiting the fourth iteration of FHIR 4 because future changes will now be backward compatible. "Applications that implement the normative parts of R4 no longer risk being non-conformant to the standard," said FHIR Product Director Grahame Grieve on the FHIR blog. Grieve also noted that in addition of the base platform several key piece of FHIR are also now normative, including the RESTful API, the XML and JSON formats, the terminology layer, the conformance framework as well as Patient and Observation resources.
